at NOWTV, we currently have a bespoke Salesforce inbound integration (creating accounts, contact etc), using custom code, to populate a message queue in salesforce (a custom object).
We would like to replace this with a 'standard' messaging product, such as MQ, however I cant find any documentation for a standard product that would push messages into salesforce

in essence - I'm looking for the exact opposite of the streaming API - I'd like a standard product that would enable salesforce to listen to an external queue and pick up messages.

Anyone aware of such a product?
